Published primarily for Oracle Priority Support customers, the Oracle Infogram is an unofficial news source that combines the best of the Oracle blogs, both inside and outside the firewall, links to useful Metalink notes, announcements, etc. Comments are welcome. We want this to be a place for dialog as well as news.

The Striving for Optimal Performance blog reminds us that March of 2009 is on the horizon, that time of the year when all the performance gurus converge on Dallas for the Hotsos symposium. That's why that week is known as 'slow DB week'.

Optimizer Modes

First_rows_n for an OLTP system or all_rows? Which do we use for our Oracle optimizer? It's one of those great ontological questions like dry rubbed ribs or sauce (or both)? Well, Jonathan Lewis has some incite at his Oracle Scratchpad blog. I haven't linked to his blog in a while, so you may want to read down through some of the other postings, which are always top quality (like this posting on PX Buffer, with lots of grotty internal details).

Alejandro Vargas brings us the good news that the Oracle validated RPM for Linux is available. Just add water and it will puff up like one of those little sponge dinosaurs, rearing up into a ferocious RAC-ready server.
